php function help (bad_word_cleanser)

[JonnySnip3r]

Hey guys i have a bad word cleanser function:

 

function bad_word_cleanser($string){
	// Words to filter
	$bad_words = array("blast", "bitch");

	// Replace words with
	$clean_words = array("[apple]","[banana]");

	for($i = 0; $i < sizeof($bad_words); $i++){
		srand((double)microtime()*1000000);
		$rand_key = (rand()%sizeof($clean_words));
		$string = eregi_replace($bad_words[$i], $clean_words[$rand_key], $string);
	}

	return $string;
}

 

it checks to see if any bad words are used and then chooses a random clean word to replace it with. any suggestions on how i could have this pick up the amount of words it has used and then have the ability to email the user if more than say 6 words are used. i have tried i just cant get it to work. Hope someone can help.

 

Thanks!

I think all of the POSIX functions were deprecated. You might want to consider using the PCRE ones. You might have to use preg_match() to count the number found and then search again to replace them.

function filterBadWords($str){

 

// words to filter

$badwords=array( "[naughty word removed]", "[naughty word removed]", "[no swearing please]", "[oops]", "[oops]", "[naughty word removed]", "[oops]", "[oops]" );

 

// replace filtered words with

$replacements=array( "[naughty word removed]", "[how wude!]", "[no swearing please]" );

 

for($i=0;$i < sizeof($badwords);$i++){

  srand((double)microtime()*1000000);

  $rand_key = (rand()%sizeof($replacements));

  $str=eregi_replace($badwords[$i], $replacements[$rand_key], $str);

}

return $str;

}

 

example call : $your_text_on_page = filterBadWords($your_text_from_comments);

 

that example works for me.. unsure why it wouldnt work for you.

another option is this:

 

// Filtering Function

function filterBadWords($str,$badWordsFile) {
  $badFlag = 0;
  if(!is_file($badWordsFile)) {
    echo "ERROR: file missing: ".$badWordsFile;
    exit;
  }
  else {
    $badWordsFH = fopen($badWordsFile,"r");
    $badWordsArray = explode("\n", fread($badWordsFH, filesize($badWordsFile)));
    fclose($badWordsFH);
  }
  foreach ($badWordsArray as $badWord) {
    if(!$badWord) continue; 
    else {
      $regexp = "/\b".$badWord."\b/i";
      if(preg_match($regexp,$str)) $badFlag = 1;
    }
  }
    if(preg_match("/\[url/",$str)) $badFlag = 1;
  return $badFlag;
}

 

// Function Call/Usage
if (filterBadWords($message,"badwords.txt") == 0) {
  mail("[email protected]", $subject, $message, $from);
}
header("Location: http://www.siteurl.com/index.php?p=Thank_You");

 

// badwords.txt
word1
word2
word3

 

and of course if that one doesnt work for you there is another option here:
